Re: Conditionally writing a new observation to dataset Posted 09-19-2019 09:21 AM (832 views) | In reply to hgaronfolo One possibility is to use a MODIFY statement: data run_table; snpst_dt="01NOV2018"d; run_ts=datetime(); format run_ts datetime22.3 snpst_dt yymmdd10...
If you can just add these 2 print statements to your sasiostdio.py file in your deployment, then we can see if I'm getting the log from SAS or not. Here's the diff so yo see where they go, and the output I get from it, just running SASsession(): tom64-7> git diff diff -...

Observation number 输出观测编号,也就是行号,或者说行索引;方法肯定很多,比如SAS是用_n_变量,R则可以row.names() # R code row.names(iris) # SAS code data _null_; set sashelp.class; put _n_; run; Keep unique values 这种可以分成两种情况: ...
13) What, according to you, is the main difference between reading data from the existing data-sets and reading data from external files? When reading data from an existing data set, SAS holds the variables' values from one observation to the other corresponding observation. Besides, while read...

一行为一个观测单位(observation)、一列为一个变量(variable) 4.DATA步的内置循环 DATA 步有一个底层结构,即隐含的内置循环。你不必通知 SAS 去执行这个循环,SAS 会自动执行它。 DATA 步逐行执行语句、逐条处理观测 SAS 读取第一条观测,然后针对它从头到尾运行 DATA 步(当然是逐行运行),然后以同样的方式接着处...
